Abstract :
This paper presents a novel control method for DC-DC power converters with bi-directional power flow and galvanic isolation. A high efficiency is achieved by using a minimal number of power electronic devices working in the soft switching mode. No reverse blocking switches are required. Different circuit variants can be derived from the proposed basic principle. Suitable industrial applications for the new principle of DC-DC conversion are UPS, photovoltaic applications, battery chargers, back-fire applications and auxiliary power supplies
